WATER-CLosET AND URINAL.

SPECIFICATION forming part of Letters Patent N o. 555,455, dated February 25, 1896. Application filed January 2, 1895. Serial No. 533,532. (No model.)

To all whom/,it may concern:

Be it known that I, SAMUEL WALKER LEWIS, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Water-Closets and Urinals, of which the following is a specification.

My invention relates to what are known as Siphon-jet water-closets and urinals', in which one or more jets are used, whichl will term a jet-flushing means, and has for its several objects, first, to prevent choking or clogging in the outlet-passage or to confine any such stoppage which may occur within a fixed or limited space that shall always be conveniently accessible; second, to shut off and muflie the noise made. by the jet when discharging into the trapped outlet-passage,- and by the same means to locate the jet and its supply connect-ion wholly above the bottom of the hopper or its outlet, whereby the siphon or outletpassage can be extended horizontally under the hopper to connect with the soil-pipe at any desired point without materially altering the proportions of the apparatus; third, to prevent the noise made by the unchecked discharge of air from the flush or supply pipe when driven out at the rimiushing means of the hopper. I attain these objects bythe construction illustrated in the accompanying drawings, in which- Figure l, on Sheet 1, is a central vertical section showing details of Siphon-outlet trap and location of the jet-flushing means. Fig. 2 is an external view, 'in side elevation, of the same. Fig. 3 is a Vertical cross-section of Fig. 1 on the linex a'. On Sheet 2, Fig. 4, is a view in side elevation, partly in section, to illustrate one method of supplying the rimflushing means 'and excluding the air therefrom. Figs. 5 and 6 are external views, in side elevation, to illustrate modified applications of both jet and rim iiushing means.

The same letters of reference indicate identica-l parts in all the Views.

The receiving hopper or bowlA is provided with an upper or rim flushing means, which may be hollow and perforated, as shown at B, or otherwise, and with sloping walls or sides terminating in an outlet into a trapped passage E, F or siphon E F G. The lower t 's l edge of the dividing-wall C forms the seal at the dotted line 3, and the bend of the passage or Siphon at K forms the trap, weir or dam which maintains the normal level of water in the hopper A. The upleg E F of the trapped outlet-passage is divided into at least two parts or sections, preferably of unequal crosssectional areas, the upper part, F, being the largest, and preferably adapted to receive the jet-discharge directly into it. and smaller part or section, E, is preferably arranged below the jet-outlet O and to lead from the hopper-outlet to the larger section, F, at such an angle as to directthe contents of the hopper toward and within or across the line and force of jet-discharge. Furthermore, the deflection or angle E F of the upleg enables me to carry the wall of the hopper straight down aud thus materially increase the length of water-surface where most needed in the hopper.

At the junction of said sections E F, I preferably form an offset or ledge I, from which -the jetpipe O discharges, whereby the contents of the hopper A is more easily directed into the larger space F and over the jet-discharge, but the bottom wall of the section E could be extended to intersect the lower wall of section F, as shown by the dotted line if, without changing the elements of the invention, and the jetor jets might be discharged upwardly from the side or sides of said upleg instead of directly underneath. The section E being the smallest part of the trap, what passes through it directed toward the jet-force will easily pass through the larger portions of the trap or passage. Therefore should any large substance be carelessly thrown into the hopper and choke the outlet-passage or si phon such stoppage will be limited to the length of the section E and easily accessible from the hopper-outlet at O D.

I preferably make the outlet-passage in the usual siphon form, as shown at G, G', and G2, whereby the tortuous passage thus formed facilitates the priming to produce siphonic action; but said tortuous passage is not an elcment of nor essential to my invention, and the downleg of the siphon or passage can be modified, as in Fig. 5, or in any suitable way.

elevating the jet fiushing means above the bottom D of the hopper I have less re- The lower IOO sistance to overcome in the initial action when the jet first discharges into the trap. Hence I can operate with a smaller jet, prime the siphon more quickly and secure a more copious doWnWash on the Walls of the hopper. In other Words, I increase the force, reduce the jet-Waste and increase the ri in-liush Without increasing the quantity of water used. Furthermore the jet action being wholly beyond the point of seal at C, shut off by the intervening wall C of the hopper and the flow of water up the passage E, its noise is oompletely muied and cannot be heard.

Another important advantage of locating the jet and its supply connection above the bottom of the hopper is that the downleg or outlet-passage can be extended horizontally, so as to connect with the soil-pipe at any desired point, which is impossible with the old construction in this class or type of closets, as shown by the dotted lines at d, Fig. l, and this enables me to make my closets with differently-located outlets, whereby they can be substituted for other closets Without having to tear up floors or change the location of soilpipe connections.

In Fig. 2 the rim flushing means., for the purpose of illustrat-ion, is shown as supplied through the usual branch at P, but with such construction the air in the pipe V is violently discharged with the water at the rini B, causing a verydisagreeable noise, to avoid which I trap the conduit leading to the rini flushing lneansand also make it longer than the conduit leading to the jet flushing means, whereby the longerconduit causingniorefrictiouresistance will deliver the Water more quietly at the rim and present more resistance to the escape of air, but to secure the best results the conduit leading to the upper or rim flushing means, should be more deeply trapped than the jet ushing means, and to obtain this result I preferably1 separate the rim and jet supplies above the normal level of the water in the hopper, as shown by dotted lines y y, in Figs. 4, 5 and 6, Wherebythe normal level of Water at y y in the rim-conduit is relatively higher and its trap deeper than the normal height and depth of Water in the jet-conduit R, which is at the same height as at the dotted line W' L in the hopper. Hence in operation the resistance to be overcome in the rim-conduit, which forms the loop P' I2 P3, is so much greater that all the air in the supply or flush pipe is easily and noiselessly expelled through the jet outlet or outlets into the trap, when the water having filled the supply or fiush pipe and conduits, the increasing pressure, which is then equal in all the conduits, causes the Water to also ow freely through the rim flushing means, which overflow completely fiushes down the walls of the hopper without any noise other than the slight ripple caused by the water Iiowing into the outlet at C D. This feature of separate Water-sealed supplyconduits of unequal depths of seal I do not l' n., Y. f N.

limit to any particular location or formation of jet flushing means, provided the conduit having least depth of seal leads to the jet iushing means and the conduit having greatest depth of seal leads to the rim, whereby the air will pass through the conduit of least depth and resistance'and thus escape through the jet flushing means.

In Fig. 4 the supply connection T is vertical and divided into two conduits, the jetconduit R leading directly to the jet and its Water-line W L being the same as in the hopper. The rim-conduit P' P2 P3 passes down on one side of the apparatus and up on the other side, as indicated by dotted lines, its loop forming a deep trap in which the depth of water is indicated by the dotted line y y.

In Figs. 5 and 6 the closet is supplied through a horizontal connection T2, the rimconduit leading preferably from the under side of said supply-horn, so that the air may pass over and beyond the entrance to said conduit and thus more easily be forced out through the jet iiushing means. In Fig. 5 both jet-conduit R and rim-conduit P P2 P3 are arranged on the same side of the closet. In Fig. G the jet-conduit R passes down on one side and the rim-conduit is trapped by a loop on the other side, as indicated by dotted lines from P to PS Another modification would be to extend the rim-conduit horizontally from P2 on one side, thence around the hopper and up on the opposite side to its outlet at P3.

In all the views I have shown an opening at N in the bend S of the conduitR below the jet, which opening may be closed by a plug or otherwise.

In operation ,when the cistern-valve or other source of supply is opened the water' flowing into the pipe V drives the air before it through the conduit R and jet-pipe O, which passage, as shown by the construction illustrated in Figs. 4,5 and 6,0ffers the least resistance and is the most direct outlet. Thus the compressed air in the supply-pipe assists the initial action of the device, while in the old construction shown at P, Figs. l and 2, its force would be wholly lost in a noisy, unchecked discharge at the rim. As soon as the air is expelled from the supply or flush pipe V and said pipe is filled with Water, a copious overflow through the more deeply `trapped rim-conduit and down the Walls of the hopper takes place simultaneous with the discharge of water from the jet-pipe O, but owing to the elements of construction described, and a proper proportion of the several parts, there is no noise other than the gentle ripple of the water into the outlet C D.

It will be observed that the bend of the conduit R at S is not above the level of the seal, as indicated by the dotted line 3. This is essential that the depth of seal be maintained at least until the Water in the hopper recedes to th@ level of said dotted line 3.
